    Data Scientist and R Expert

    United States - Last active: 1 day ago - Tests: 7

    I have 7 years of experience in data analysis. I'm the Chief Data Scientist and founder of Cabaceo.com, a data science consulting company in Ann Arbor, Michigan, US. I also teach people how to do data science using the R programming language at www.MasterR.org, where you can receive high quality training materials for free. I used to work as an analytic consultant for FICO, where I built scorecard for Picture People to predict customer response rate to their marketing campaigns, which doubled their ROI. I also built customer segmentations for Canadian Tire Bank, which gave the executive team a holistic understanding of their customers for the first time and resulted in a chapter of a book. More recently, I have built a linear regression model to explain the relationship between interest rate of peer-to-peer loans and borrowers' characteristics using data from LendingClub, a two-level clustering-and-randomForest model to predict human physical activities using smartphone data, a logistic regression optimization based on precision and recall, a R-implementation of the cross-sectional regression and quintile-portfolio construction methods published in the Journal of Economic Literature. I have a masters degree in Biostatistics from the University of Michigan and a bachelor's degree in mathematics from New College of Florida. I'm an avid MOOC taker, constantly learning new techniques and tools in data science and machine learning. I took all the courses in data science, statistics and machine learning from Coursera, Udacity and Edx. I respond all my messages in less than 24 hours.

    Serbia - Last active: 28 days ago - Tests: 2

    Learn through data analysis, would be the tag line for me. I am a data scientist with business intelligence and text analysis background. I am also a JAVA/php/javascript developer, like databases, have a PhD (if important). Strong incentive to build systems that analyse and learn from data. I've done this for the last 8 years in academia and industry, and will try to do it for a long time (still only 30).

    Sr. Project Planning, Scheduling and Data Analyst

    United States - Last active: 3 months ago - Tests: 7

    Hello! Do you have a project you NEED to keep on schedule and deliver on time? For every milestone you miss you are in danger of missing your delivery date. Schedule slips mean you reduce your profit and your customer loses confidence you can deliver when you said you would. What you need is a project plan and schedule that will help you keep track of your project. Your schedule needs start of project, durations for each task, and a good logical network of predecessors and successors. Once you have that you need to baseline your project so at the end you can analyze where the bottleneck might have occurred. Let me help you build a realistic schedule so you can meet delivery on schedule which will help you deliver on budget. I have helped major aerospace companies achieve their goals on delivery saving them lots of $$$. I've also started helping out small companies so they can grow and profit as they implement better planning for their projects and products. Remember, you need to keep track of your projects and your production/services to optimize your business. You need my help whether your business is virtual or you have a physical location. Let me know if you have any questions. Regards, Minerva
